Unlocking innovation in the sport industry through additive manufacturing
Fast changing customer demands and rising requirements in product performance constantly challenge sports equipment manufacturers to come up with new and improved products to stay competitive. Additive Manufacturing (AM), also referred to as 3D Printing, can enhance the development of new products by providing an efficient approach of rapid prototyping. This research aims to analyse the current adoption of AM technologies in the innovation process of the sports industry i.e. level of awareness; how it is implemented; and it impact on the innovation process. Literature research shows that AM brings many possibilities to enhance the innovation process, and case studies indicated several obstacles that hinder the technology from fully unfolding. AM is still at the early stage of entering the sports equipment industry and its potential benefits have not been fully exploited yet. The findings generated from the research of real life practices show that AM provides several benefits when it comes to the innovation process, such as a faster development process, an optimised output, as well as the possibility to create new designs. However, companies are not yet able to enhance the innovation process in a way that leads to new products and new markets with AM. Limitations, including a small range of process able material and an inefficient mass production, still restrain the technology and lead to unused capability. Nevertheless, future prospects indicate the growing importance of AM in the innovation process and show that its advancement paves the way to new and innovative products
Comparison of screening for pre-eclampsia at 31-34 weeks' gestation by sFlt-1/PlGF ratio and a method combining maternal factors with sFlt-1 and PlGF
Objective: To estimate the patient-specific risk of preeclampsia (PE) at 31-34 weeks’ gestation by a combination of maternal characteristics and medical history with multiple of the median (MoM) values of serum placental growth factor (PLGF) and serum soluble fms-like tyrosine kinase-1 (sFLT-1) and compare the performance of screening to that achieved by the sFLT-1 to PLGF ratio.
Methods: This was a prospective observational study in women attending for a third-trimester ultrasound scan at 31-34 weeks as part of routine pregnancy care. We estimated the performance of screening of PE with delivery within four weeks of assessment (PE at <4 weeks) and PE from four weeks after assessment and up to 40 weeks’ gestation (PE at 4w-40GW) in screening by the sFLT-1 to PLGF ratio and by a to PLGF ratio and by a method utilizing Bayes theorem to combine maternal factors and MoM values of sFLT-1 and PLGF. The significance of difference in performance of screening between the method utilising Bayes theorem and that of the sFLT-1 to PLGF ratio was assessed by comparison of the areas under the receiver operating characteristic curves (AUROC).
Results: The study population of 8,063 singleton pregnancies included 231 (2.9%) that subsequently developed PE. In the prediction of delivery with PE at <4 weeks the performance of the method utilising Bayes theorem was similar to that of the sFLT-1 to PLGF (AUROC: 0.987, 95%CI 0.979-0.995 vs. 0.988, 95%CI: 0.981-0.994; p=0.961). and at fixed fixed screen positive rate (SPR) of 3.9% the detection rate (DR) was 87.1% for both methods. In contrast, the performance of screening for delivery with PE at 4w-40GW was better with the method utilising Bayes theorem than with the sFLT-1 to PLGF ratio
(AUROC: 0.884, 95%CI 0.854-0.914 vs. 0.818, 95%CI: 0.775--0.860 ; p<0.0001) and at total fixed SPR of 25.7% the DRs were 84.4% vs. 73.0%.
Conclusion: At 31-34 weeks’ gestation the performance of screening for PE at <4 weeks from assessment by the method utilising Bayes theorem is similar to that of the sFLT-1 to
PLGF ratio, but the former is superior to the latter in prediction of PE >>4 weeks
Plastic surgery in the European Union: A study of development, training, manpowerplanning and migration
The aim of this study is to clarify the role of plastic surgery in the European Union (the
former European Connnnnity). The idea is that this will lead to a better understanding of
the specialty among laymen., colleagnes and healthcare officials. To this end, the historical
development of the specialty and its present day problems, including the European
Unification and border zone activities by other specialties, will be discussed. Whenever
possible, links and counections with the historical development and the boundary problems
will be sought in the discussion of the subject under review, which subjects will be
categorized under severa! headings. Also, the training in plastic surgery will be analysed
and a comparison will be made concerning the various EU countries (the fonner EC
countries). Furthermore, the effects of European Unification including the possible need for
European standardization of contents and training of the specialty and manpower planning
and migration within Europe will be discussed. Finally, reconnnendations will be made for
the future development of the specialty.
Plastic surgery is an intrigning specialty. On the one hand it has experienced a tremendous
development, on the other hand there are problems, due to its complexity (Luce, 1993),
which require clarification. The need to discuss these problems is partly caused by the
increasing media coverage of the aesthetic side of the specialty of plastic surgery and by the
boundary problems with other specialties
QuantifyPolarity, a new tool-kit for measuring planar polarized protein distributions and cell properties in developing tissues
The coordination of cells or structures within the plane of a tissue is known as planar polarization. It is often governed by the asymmetric distribution of planar polarity proteins within cells. A number of quantitative methods have been developed to provide a readout of planar polarized protein distributions. However, previous planar polarity quantification methods can be affected by variation in cell geometry. Hence, we developed a novel planar polarity quantification method based on Principal Component Analysis (PCA) that is shape insensitive. Here, we compare this method with other state-of-the-art methods on simulated models and biological datasets. We found that the PCA method performs robustly in quantifying planar polarity independently of variation in cell geometry and other image conditions. We designed a user-friendly graphical user interface called QuantifyPolarity, equipped with three polarity methods for automated quantification of polarity. QuantifyPolarity also provides tools to quantify cell morphology and packing geometry, allowing the relationship of these characteristics to planar polarization to be investigated. This tool enables experimentalists with no prior computational expertise to perform high-throughput cell polarity and shape analysis automatically and efficiently
J Interpers Violence
Homicide-suicide incidents involving child victims can have a detrimental impact on survivors of the violence, family members and friends of the decedents, and other community members, but the rare occurrence of these acts makes using quantitative data to examine their associated antecedents challenging. Therefore, using qualitative data from the 2003-2011 National Violent Death Reporting System, we examined 175 cases of homicide-suicide involving child victims in an effort to better understand the complex situational factors of these events. Our findings indicate that 98% of homicide-suicides with child victims are perpetrated by adults (mostly parents) and propelled by the perpetrators' intimate partner problems, mental health problems, and criminal/legal problems. These events are often premeditated, and plans for the violence are sometimes disclosed prior to its occurrence. Findings provide support for several theoretical perspectives, and implications for prevention are discussed.CC999999/Intramural CDC HHS/United States2019-02-01T00:00:00Z26385898PMC4795978vault:1634
